Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8626738, here are decompositions:

5 + 8626733 = 8626738
41 + 8626697 = 8626738
47 + 8626691 = 8626738
251 + 8626487 = 8626738
269 + 8626469 = 8626738
317 + 8626421 = 8626738
347 + 8626391 = 8626738
389 + 8626349 = 8626738

Showing the first eight; more decompositions exist.
